peptide-geo-monitor v0.1.0: internal AI-visibility dashboard (#1)

New internal plugin: weekly LLM probes of core peptides (Perplexity sonar + GPT/Gemini-search via OpenRouter/CF gateway) -> custom table -> wp-admin trendline + standings. Provider interface + cost ledger w/ hard $5/mo cap + collector/panel seam (AI-visibility only). v1 = AI-visibility only.
